As an extension to this question here Linking JavaScript Libraries in User Controls I was after some examples of how people are concatinating & minifying javascript on the fly OR at build time. I would also like to see how it then works into your master pages.
I don't mind page specific files being minified and linked inidividually as they currently are (see below) but all the js files on the main master page (I have about 5 or 6) I would like concatenated and minified.
Bonus points for anyone who also incorporates CSS concatenation & minification! :-)
Current master page with the common js files that I would like concatenated & minified:
<%@ Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %>
<head runat="server">
... BLAH ...
<asp:ContentPlaceHolder ID="AdditionalHead" runat="server" />
... BLAH ...
<%= Html.CSSBlock("/styles/site.css") %>
<%= Html.CSSBlock("/styles/jquery-ui-1.7.1.css") %>
<%= Html.CSSBlock("/styles/jquery.lightbox-0.5.css") %>
<%= Html.CSSBlock("/styles/ie6.css", 6) %>
<%= Html.CSSBlock("/styles/ie7.css", 7) %>
<asp:ContentPlaceHolder ID="AdditionalCSS" runat="server" />
</head>
<body>
... BLAH ...
<%= Html.JSBlock("/scripts/jquery-1.3.2.js", "/scripts/jquery-1.3.2.min.js") %>
<%= Html.JSBlock("/scripts/jquery-ui-1.7.1.js", "/scripts/jquery-ui-1.7.1.min.js") %>
<%= Html.JSBlock("/scripts/jquery.validate.js", "/scripts/jquery.validate.min.js") %>
<%= Html.JSBlock("/scripts/jquery.lightbox-0.5.js", "/scripts/jquery.lightbox-0.5.min.js") %>
<%= Html.JSBlock("/scripts/global.js", "/scripts/global.min.js") %>
<asp:ContentPlaceHolder ID="AdditionalJS" runat="server" />
</body>
Used in a page like this (which I'm happy with):
<asp:Content ID="signUpContent" ContentPlaceHolderID="AdditionalJS" runat="server">
<%= Html.JSBlock("/scripts/pages/account.signup.js", "/scripts/pages/account.signup.min.js") %>
</asp:Content>
EDIT: What I'm using now
Since asking this question, Microsoft have released their own JS & CSS compression library called Microsoft AJAX Minifier, I'd definitely recommend checking it out. It includes MSBuild tasks which are the duck's nuts.
